# Note: Doc is at http://docs.pylint.org/output.html#reports-section
# Note: This format only affects output format text, but not html.
# Note: The default format is:
#       {C}:{line:3d},{column:2d}: {msg} ({symbol})
# Note: The vim quickfix support by default recognizes the following format:
#       {path}:{line}: ...

# disable everything first and then re-enable specific checks. For example, if
# you want to run only the similarities checker, you can use "--disable=all
# --enable=similarities". If you want to run only the classes checker, but have
# no Warning level messages displayed, use "--disable=all --enable=classes
# --disable=W".
# Note: The too-many-* messages are excluded temporarily, and should be dealt
#       with at some point.
# Note: wildcard related messages are excluded because the original external
#       interface uses wildcard imports and we cannot change that without
#       breaking compatibility. We could move the message control statements
